Questions and Answers

What is a primary characteristic of a one-sided hypothesis?

  • It specifies the expected direction of difference. (correct)
  • It allows for the possibility of effects in both directions.
  • It indicates no clear expectation of the direction of effect.
  • It requires clinical equipoise to be valid.

    • When should a two-sided hypothesis be utilized?

  • When conducting non-randomized trials.
  • When previous studies showed a definitive result.
  • When the direction of the effect is uncertain. (correct)
  • When researchers have a strong expectation of the outcome.

    • What does clinical equipoise require for conducting a clinical trial?

  • Preference for one treatment based on prior studies.
  • Absolute certainty regarding treatment effectiveness.
  • Genuine uncertainty in the expert community about treatment benefits. (correct)
  • A unanimous agreement among doctors about treatment options.

    Study Notes

    Research Questions and Design

    • Developing good research questions, hypotheses, and objectives can be challenging.
    • Critical appraisal of the research question is vital for applying findings to clinical practice.
    • Dedicating resources, time, effort to developing elements (question, hypothesis, objective) is essential.
    • Well-developed elements guide the project, influencing result interpretation, & impact publication efforts.
    • Researchers should use available tips and guidelines to formulate key research components effectively.

    FINER Criteria

    • Feasible, Interesting, Novel, Ethical, Relevant

    Origins of Research Questions

    • Personal interest/experience/clinical observation/inspiration
    • Immersion in literature is crucial for refining questions.
      • Systematic literature review
      • Incremental progress - fundamental for evolving research questions.
      • Builds upon existing knowledge, refining methods, and expanding boundaries of understanding.
      • Replications - helpful; especially with better methods/different groups.
      • Theories - explain connections between factors; suggest ways to improve interventions.
      • Stakeholder viewpoints are important (e.g., service users, carers).

    Hypothesis

    • A testable explanation for a phenomenon.
    • Core of scientific method
    • Any empirical study should have a hypothesis that clarifies the association between phenomena.
    • In a study, more than one hypothesis is allowed, but one should be the main focus.
    • Qualitative and descriptive studies may lack hypotheses but still have a specific research question.
    • Example hypothesis - (e.g., people who report experiences of childhood physical abuse score higher on a measure of suspiciousness).

    Types of MH Research Questions

    • Aetiology & Mechanisms (understanding how and why mental health problems arise)
    • Treatment (developing methods to prevent or alleviate mental health problems).
    • Experiences (examining the lived experience of mental health problems).

    Designing a Protocol

    • Principles: start with a clearly defined question, write a protocol, methods have pros and cons
    • Good designs are collaborative.
    • Design should fit current knowledge and evidence.
    • Keep it simple; publish protocol

    Protocol Structure:

    • Introduction: context, current evidence, and rationale.
    • Aims & Objectives: key research question, hypothesis (if applicable).
    • Methods: methods with relevant specifics (e.g., sample, procedures, data collection methods, data management and analysis, ethical considerations).
    • Analysis plan
    • Dissemination plan: strategy for distributing findings.
    • Timing, staffing, ethics, research governance, costs

    Other Protocol Elements

    • Participants and Sampling/Recruitment
    • Interventions and Controls
    • Data Management and Analysis
    • Ethical Considerations & Informed Consent
    • Strengths and limitations
    • Timeline
    • Budget (or funding sources)
    • Potential pitfalls and solutions
    • Dissemination plan
    • Dissemination goals, objectives (e.g., goals for dissemination, timeline, responsibilities, policy and practice implications, evaluation, resources, ethical considerations)
    • Public and Patient Involvement (PPI)

    Strengths and Weaknesses of a Research Protocol

    • Strengths: reviews existing research, explains gaps in research, includes PPI aspects, contains an aim, contains methods section, describes the inclusion criteria or details.
    • Weaknesses: vague language and criteria/variables, vague or inappropriate age groups, lacks reliability in how the study will be conducted, lack of explanation of key terms, too vague, no clear hypothesis, no quantifiable aim/hypothesis, no objective, no method of analysis, no review of confounding variables, no clear timelines.

    Additional Elements

    • State level of significance, specify statistical test and justify methods, describe handling of variables, review possible confounding variables
    • Clearly defined approach to data collection (e.g., thematic analysis, grounded theory).
    • Mention of appropriate software for analyses.
    • Outline dissemination plan (target audience, channels).

    Dissemination

    • Target Audience/method or channels
    • Other researchers, clinicians, patients, service planners, policy makers, general public
